My invention aims to provide improvements in buttons for garments and the like. In the drawings which illustrate preferred embodiments of my invention Figure 1 is a vertical section through a button installation with a cap attached to the head of the button;

Fig. 2 is a side elevation of the button shown in Fig. 1;

Fig. 3 is an under side view of the button shown in Fig. 2;

Fig. 4; includes a side elevation and a plan view of the attaching part of theinstallation;

Fig. 5 is a section through a button in stallation, the cap piece being omitted;

Fig. 6 is a side elevation of the button shown in Fig. 5; and

Fig. 7 is an under side view of the button shown in Fig. 6.

Referring to my invention as illustrated by the drawings, I have shown improvements in buttons for use on garments and the like such as overalls, jackets, etc.

The button installation illustrated in Figure 1 includes a button A, a carrying medium 1 and an attaching member 2. The button is located at one side of the carrying medium and has a head 3, a cap 4:, a shank 5, a base 6 and sharp pointed attaching prongs 7. All of the button, except the cap 1, is pressed from a single piece of sheet metal.

One method by which my one-piece button may be made is to press the central portion of a blank between various dies until it is shaped in a manner shown in Fig. 2. The flanged base 6 may be formed by crimping the wall of the shank inwardly from an initially larger diameter or the material may be rolled outwardly at the point where it is desired to form the base 6 and then the flanges may be squeezed together.

The prongs 7 may be out from an initially formed cylindrical portion, and extend from the inner edge of the doubled under flange oi the base. It should be noted that I have located the attaching prongs 7 in alignment with the wall of the shank 5 thereby to be back-supported by. the wall when they are thrust through the carrying medium 1.

The button A may be attached to the carrying medium by pressing the prongs 7 through the carrying medium into engagement with the attaching member 2 located at the op posite side or the carrying medium, as shown in Fig. 1. This particular attaching member 2 (Figs. 1 and a) is pressed from a single piece of metal and has a curved anvil portion 8 and an inturned peripheral flange 9. When the button is attached, the prongs 7 are deflected outwardly by the anvil portion 8 and their ends are clenched against the flange 9.

Tn some instances it is desirable to provide a button, of the type above described with a head which appears imperforate or which may bear a design or other marking. There- :lore, T have shown the button A 1n Flgs. 1, 2 and 3 as having a cap piece 10 secured to the head 3 oi the button.

It the cap 10 is not desired, the button may be made as shown in Figs. 5, 6 and 7.

In both types of buttons shown the attachment is the same. The attachment is simple, strong and durable and the only per forations are those made by the prongs 7. These perforations do not weaken the at tachment, because an annular portion of the carrying medium 1, outside of the perforations made by the prongs, is gripped tightly between the base 6 of the button and the flange 9 of the attaching member 2 to prevent tearing, as shown in Figs 2 and 5.

While I have illustrated and described preferred embodiments of my invention, 1 do not wish to be limited thereby, as the scope of my invention is best defined in the following claims.

Claims:

1. A button having a head, a shank beneath said head, a number of attaching prongs extending beyond the said shank for passage through a carrying medium to secure the button to the carrying medium and a laterally extended flange located at a point between where the shank ends and the attaching prongs begin.

2. A. button having a head, a shank having one end connected to said head, a base flange at the other end of said shank of larger diameter than said shank to provide a supportengaging surface outside of the periphery of said shank and a number of attaching prongs s aced inwardly from the periphery of said ange to provide means for attaching the button to a support.

3. A button having a head, a shank having one end connected to said head, a base flange of double thickness of material at the other end of said shank of larger diameter than said shank to provide a support-engaging surface outside of the periphery of said shank and a number of attaching prongs extending from said flange in a direction away from said shank but in alignment with the peripheral Wall of said shank to be back-supported thereby when forced through a carrying medium.

4. A one-piece sheet metal button having a head, a shank pressed from the center of said head, a flange extending outwardly at the free end of said shank in spaced relation to the head and doubledunderneath to provide a double thickness and a number of sharp pointed attaching prongs extending from the free edge of the underneath portion of the flange.

5. A fastener installation comprising, in

combination, a fastener member, a carrying medium and an attaching part, said fastener member being located at one side of the carrying medium and the attaching part being located at the opposite side, a number of attaching prongs extending from said fastener member through the-carrying medium and Erong turning and clenching means provided y the attaching part and receiving and clenching said attaching prongs'to secure the parts of the installation together.

6. A button installation comprising, in combination, a one-piece button, a carrying medium and a one-piece attaching part, said button being located at one side of the carrying medium and the attaching part being lo- .cated at the opposite side, a number of attaching prongs formed integral w th and extending from said button through the carportion through the carrying medium into engagement with the attaching part, an an-- nular flange extending laterally outwardly from a point Where the attaching prongs pass through the carrying medium and engaging the carrying medium and prong turning and clenching means provided by the attachin part and clenching the prongs outwardly an downwardly thereby to grip the carrying medium tightly between the annular flange of the fastener member and the attaching part. 7

In testimony whereof, I have signed my name to this specification.
